BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 508,056, dated November7, 1893. Application filed August 4, 1892` Serial No.442,157. (Nomodel.)

To all whom t may concern:

f Be it known that I, GARY B. SMITH, a citi' .zen of the United States,residing at Wolcott, 1n the county of Wayne and State of New York, haveinvented a new and useful Bed- 1Iottonn, of which the following is aspecificaion.

My invention relates to improvements in- In the drawings; Figure 1 is aplan view of a bed-bottom embodying my improvement. Flg. 2 is asideview. Fig. 3 is a longitudinal section, showing the head-rests and legsor ksupports folded. Fig. 4 is a detail View of a Section of one of thestrands, showing the concentric coils. Fig. 5 is an end view showlng thenotches for the attachment of the strands to the frame. Fig. -6 is adetail View of one of the looped or double cross-strands or stays.

The frame l comprises, essentially, the parallel side-bars 2, andtheend-bars 3, which are secured upon the upper surfaces of the side-barsso that the upper edges of the endbars are above the plane of theside-bars. To the inner sides of the side-bars, near their extremities,are pivotally connected the legs 01` supports 4, the head-rest frames 5being pivotally connected, near their lower ends, With said legs orsupports, and being connected in pairs by the cross-bars 6. Theheadrests consist of the side-pieces 7, which are adapted to rest attheir lower ends upon the licor when the bed is in its operativeposition, said side-pieces being extended the same distance below theirpivotal point as the legs or supports; and said side-pieces areconnected, at their upper ends, bythe transverse bar 7". Additionalcross-bars 8 are provided at intermediate points of the sideibars, for apurpose to be described hereinafter.

The bed-bottom comprises, essentially the y longitudinal strands 9, andthe transverse strands or stays lO. The longitudinal strands areattached .at their ends to the end-bars of the frame, and the transversestrands or stays are connected solely to the longitudinal strands andare interlaced between the same to hold them at the desired separation.

The strands which I prefer to use, and which I have shown in connectionwith the drawings, consist of coils of fine wire; and while single coilsmay be used with advantage, I prefer to employ double coils orconcentric coils, which consist of a core or interior coil ll, andashell or exterior coil 12, as shown clearly in the detail View, Fig. 4,each being closely or compactly coiled to permit ot equal extension. Thetransverse strands or stays are looped or doubled, the closed end of theloop being engaged with one of the sidestrands, and the free ends of theloop being coiled in opposite directions around the oppositeside-strands. The sides of the loop are twisted together regularly inone direction and each side is passed alternately under and oversuccessive longitudinal strands, whereby, at the intersections of thetransverse strands or stays and a longitudinal strand, one side of theformer rests upon the upper side and the other upon the lower side ofthe longitudinal strand, thus uniting allof the longitudinal strands andcausing them to bear mutually the pressure of the superincumbent weight.

In Fig. 1 the longitudinal strands are shown as connected to theend-bars in the simplest manner, namely, by placing their extremities indepressions or perforations in said bars, but other ways of securing thestrands to the frame may be employed, the preferred manner ofaccomplishing this being indicated in Fig, 5. In this construction, theouter surface of the end-bar is provided with a longi y the longitudinalstrands are not necessarily formed 0f single lengths, but maybe integralIOO as indicated in the above-mentioned figure, two or more strandsbeing connected together and secured in place by engaging their loopswith the channels in the end-bars.

It will be noted that the transverse strands or stays are disposedalternately in opposite directions, namely, the closed ends of the loopsare alternately enga-ged with opposite side-strands, thus adding to thestrength and firmness of the bed-bottom, and equalizing the weights ofits parts.

The intermediate transverse bars which are above described in connectionwith the headrests, act as stop bars to engage theilongitudinal strandsin proximity to the end-bars to hold said head-rests and the legs orsupports in their operative positions. The manner in which said restsand `supports are folded is clearly shown in Fig. 3.

Having thus described my invention, what my own I have hereto aiixed mysignature in 3 5 the presence of two witnesses.
